This light is the Mercedes-AMG GT63 S of grow lights. real talk.....


After reviewing and looking into many lights I choose HLG. Scorpion
has very even coverage. The added red is great for the growth of the stems and roots. Providing a great addition to the quality and yield. Light is very well made of top quality material. The diodes are the top bin. Differences in LED bins are these so-called general bins are like a dollar burger, the top bin is the cream of the crop. I'm glad I did the research and asked the questions before making the HLG choice. Best choice I don't think there is a better light on the market.


If you haven't seen this light it will blow you away literally at a 100% it is too much best grow light I have used in 20 years


Got this shipped to me in Alaska, arrived perfectly intact. Amazingly bright!! I had to dim it to prevent light stress. Plants are getting used to it now, and will hopefully withstand 100% strength soon. I am so glad that I took the plunge. If you have any questions, the customer service is great, they have knowledgeable answers.
6 out of 5 stars!
